  1. History of Science on Computer Historian? · · Score: 1

    I knew a fellow in college who was heading to graduate school to study History of Science. I gathered it was an established sub-field. You might look for universities that have some professors who specialize in that. Even if you didn't end up doing that for your career, it would be a nice liberal arts major.

  2. Lenses on Even Tinier SVGA Color Display · · Score: 2

    It doesn't have to sit directly in front of your eye. Lenses work very well for magnifying things.
    Fiber optics and mirrors can move images around.

  3. Bond on Ikonos 1 lost in space · · Score: 1

    I'm surprised none of you have blamed an evil bald industrialist with a white Persian cat...

  4. Tracking on 3D LCD Screen without Glasses · · Score: 3

    The tracking device looks like a slightly modified RingMouse (now called the Owl by some resellers, I think.) It uses ultrasound time of flight, emitted from the tracker and received by three speakers, to track 3D position, and an infrared receiver for button clicks.

    I sincerely doubt that the tracking is being used to adjust the lens (be it holographic or lenticular, I don't know.) Even with a perfect lens, you want to track the position and orientation of the head so that you can adjust the 3D rendering view accordingly. Without the headtracking, the image of the object will distort as you move away from the sweet spot, i.e., the point in real space that corresponds to the virtual view point. With the head tracking, the object appears to remain still, and you can move back and forth to get parallax, look at the sides, etc. With a full 6DOF tracker, you can even tilt your head and the view remains perfect. With the tracker used here, you will not be able to do that.
